The Cwmorthin Tramway was a 1 ft 11+1⁄2 in (597 mm) industrial tramway in North Wales, which connected the Ffestiniog Railway to the Cwmorthin Quarry and later the Conglog Slate Quarry. It was built in the 1840s or 1850s, rising through two inclined planes to reach the main Cwmorthin Quarry mill and its internal incline which rose from floor 1 to floor 8. In 1874, it was extended, rising up through a third incline to the Cwmorthin Lake level and continuing along the valley floor to reach the Conglog Quarry. The tracks to Conglog were abandoned in the 1920s and the rest of the tramway ceased to be used from the onset of the Second World War.
